The Padishah Emperor was the title of the hereditary rulers of the Imperium and the Known Universe, coming from the ancient Persian meaning "Master of Shahs". They were also known as "Emperors of the Known Universe". The title of Padishah Emperor was taken by the head of House Corrino after the Battle of Corrin. It was used by the head of that House for more than 10,000 years. The title ceased to exist after the death of Leto II, when the Imperium was dissolved.
